Weld Inspection
AREVA
has developed a cutting-
edge tool for nuclear reactor vessel
inspections that optimizes both the safety
and reliability of operations for nuclear
facilities. The automated tool, known as
the Lower Girth Weld Inspection Tool
(LGWIT), allows plant personnel to
perform inspections remotely through
narrow gaps in the reactor vessel internals.
The tool’s remote operation replaces
the need for direct human intervention.
This is both more efficient and contributes
to significant cost savings for each
inspection performed. The inspection
of reactor vessel internals is essential
to ensure the safe, long-term operation
of nuclear power plants. This is also a
key requirement in the license renewal
process.
AREVA designed this tool to
meet the criteria of the Electric Power
Research Institute’s Materials Reliability
Program and the U.S. Nuclear Regulatory
Commission’s NUREG 1766 (Safety
Evaluation Report Related to the
License Renewal of North Anna Power
Station, Units 1 and 2, and Surry Power
Station, Units 1 and 2) regulation. The
successfully proven LGWIT tool is
currently in use by AREVA at outages for
two major U.S. utilities.

New Technology Meters
Otek Corporation
has released a
new series of meters - The NTM (New
Technology Meters). This new series
changes the way we look at digital
bargraph meters and introduces an
exclusive input failure alert and alarm
system.
The new series of meters offers
operator friendly digital display as well
as an automatic tricolor bargraph with
color set point. There are no moving
parts in the design, making it durable and
reliable. High quality products allows
OTEK to offer an industry unique lifetime
warranty.
A featured model in the series is
the NTM-3. This meter is ANSI 4"
switchboard replacement meter. The
NTM-3 is available in plastic or metal
housing and meets military or nuclear
specifications. You can build up to
three channels to house in one meter.
Additionally, the meters can be loop,
signal or externally powered.
You can have the visibility and
accuracy of a digital meter and the low
power consumption of an analog meter
all in one. There are many more options
available in the series.

Valve Actuator
Rotork-Hiller
has announced a
pneumatic valve actuator design break-
through that greatly reduces space
requirementswhilemeeting specifications
and regulatory requirements for critical
failsafe applications in the nuclear power
industry.
The new design incorporates the
actuator, nitrogen storage accumulator,
and all associated controls within a
compact, standalone package to provide
springless, totally pneumatic operation.
One example for a 1-1/2" stroke linear
actuator used in a plant fire control
system has envelope dimensions of only
18 x 23 x 27 inches.
Rotork-Hiller
engineers
can
configure the new actuator design to meet
customer-specific needs.

Machine Tool
Konecranes
Machine Tool Service
offers machine calibration services to
manufacturers for maintenance and
certification purposes.
With its state of the art laser measur-
ing and calibration systems, Konecranes
Machine Tool Service can increase ma-
chine performance and help manufactur-
ers prepare for planned maintenance or
satisfy requirements of qualifications and
certifications like ISO, QS and ASME
B5.54 (Methods for Performance Evalua-
tion of Computer Numerically Controlled
Machining Centers). Laser calibration
from Konecranes Machine Tool Service
optimizes machine performance, increas-
ing accuracy and repeatability when pro-
ducing close tolerance parts.
Konecranes Machine Tool Service’
laser
inspection
and
calibration
equipment is calibrated according to the
manufacturer’s recommended intervals
and traceable to NIST. Konecranes
Machine Tool Service keeps certificates
reflecting the calibration date and results
on file, so copies can be provided to their
customers upon request.
The calibration specialists at
Konecranes Machine Tool Service will
precision level and optimize the machine
tool’s geometrical orientation and inspect
its dynamic/interpolation performance.
Linear positioning and repeatability
will be compensated and verified. A
computer-generated plot can be supplied
in QS, B5.54, ISO, or any format of the
customer’s choosing.

Field Machining
POWERMAQ
has launched its first
global field services company. From its
U.S. headquarters in Portland, Ore., the
new venture will offer expert machining
and repair services for heavy industry
worldwide.
POWERMAQ USA is staffed
with professional managers, engineers,
technicians, and field machining experts.
Several of the technicians and machinists
have more than 20 years’ experience in
on-site machining. Their deep experience
includes projects in nuclear facilities, oil
and gas refineries, mining operations, as
well as subsea environments and a host of
other industrial locations.
To perform the difficult repairs
required, the POWERMAQ USA crew
is equipped with state-of-the-art portable
machine tools which are known for
peak performance in challenging on-site
repairs -- whether refacing a severely
corroded flange in a refinery, repairing
leaks to pipelines, offshore or undersea,
or doing turbine maintenance at a power
plant.
